New Wheels Noise/Vibration... help please.

New Wheels Noise/Vibration... help please.
I got a set of used Maxxim Ahead Wheels and tires in flawless condition:
Wheels can be seen here:

I installed them and took a drive. I notice a shake at 40+MHP and a "Whom, Whom, Whom, Whom" Noise coming from the wheels. The tire pressure is at 35psi all the way around. They're a 42mm offset on the EXACT same rubber that my OEM wheels use. Khumo Ecsta AST
What would cause this? Did I miss something? Do I need some sort of hub centric ring or something?
I figured this would be plug/play.

Check that you or someone tightened the lugnuts and torqued them to 108 ftlbs...also are they balanced? ...sounds kinda silly but little details can make for some big problem.

I don't have a torque wrench with me but I went at it again with a 4 way. I was able to get quite a few more turns out of the front tires. The back were pretty snug.
This greatly reduced the vibration and noise.

Sounds like the tires may be cupped. I have personally seen that kumho tires like to cup on the inside tread if not rotated often. Run your hands on the inside part of the tread and feel for some wavy tire wear

The center bore size (and offset) is the reason you can't just get 'any old wheel' and stick it on 'any old car'! From your 1st post, I'm guessing you got a deal on the wheels from someone.... what car where they used on?
One other thing - I wouldn't "go at it with a 4-way". That's a easy way to strip or break a hub bolt - mucho pain if you do. 108ftlbs isn't very much tightening at all - if you did what you say I'm nearly certain you've way overtightened the nuts.
Go buy yourself a torque wrench. The best advice ever is: Always (Alway!) use the right tool for the job!
